Abstract
In order to combine prepayment with centralized meter reading, the utility model relates to a multi-rate prepayment electric meter which comprises a central control unit, a metering module and an IC card module. The metering module is connected with the electric quantity metering signal input end of the central control unit by connecting a photoelectric sensor in series, and the IC card module is connected with the IC card read-write end of the central control unit. In order to be convenient for checking the power consumption of the electric meter by an infrared meter reading device, the first communication end of the central control unit is connected with an infrared communication interface used for outputting information about electric quantity. In order to be convenient for checking the power consumption of each electric meter in a long-distance manner, the second communication end of the central control unit is connected with a power line carrier wave modem used for connecting a multi-rate carrier wave meter reading concentrator.
Description
Technical field
The utility model relates to a kind of many rates pre payment watthour meter.
Background technology
The pre-payment electric power management system that relies on the intellective IC card technical development to get up can be realized paying dues the management mode of back electricity consumption earlier.Solved the problem of electric fees charging difficulty, but can't implement the effective management of power use and monitoring,, can not realize the robotization of " copying " " nuclear " link as functions such as the calculating of the line loss in the electricity charge accounting cycle, electric weight gather.
The utility model content
Technical problem to be solved in the utility model provides a kind of many rates pre payment watthour meter, so that pre-payment is combined with centralized automatic meter-reading.
For solving the problems of the technologies described above, the utility model provides a kind of many rates pre payment watthour meter, comprising: central control unit, by the metering module that links to each other with the electric quantity metering signal input part of central control unit of series connection photoelectric sensor, hold the IC-card module that links to each other with the IC-card read-write of central control unit.
Further, for conveniently examine the power consumption of watt-hour meter by the infrared ray meter reading device, first communication ends of described central control unit is connected with the infrared communication interface that is used to export information about power.
Further, by the long-range power consumption of examining each watt-hour meter, the second communication end of described central control unit is connected with and is used for the power line carrier modem that links to each other with many rates carrier meter reading concentrator for convenient.
The utlity model has positive effect: in (1) many rates pre payment watthour meter of the present utility model, pre-payment low-voltage power carrier automatic meter reading system organically combines centralized automatic meter-reading and two kinds of technology of prepaid, the advantage of comprehensive these two kinds of technology, when realizing the pre-payment electrical management, make system still possess remote centralized automatic meter-reading, the function of monitoring." copying " " nuclear " " receipts " comprehensive automation for power supply enterprise provides reliable technique support more.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is the circuit block diagram of the many rates pre payment watthour meter among the embodiment.
Embodiment
See Fig. 1, many rates pre payment watthour meter of present embodiment comprises: central control unit 1, by the metering module 2 that links to each other with the electric quantity metering signal input part of central control unit 1 of series connection photoelectric sensor 3, hold the IC-card module 5 that links to each other with 2 IC-card read-write of central control unit 1.
For conveniently examining the power consumption of watt-hour meter by the infrared ray meter reading device, promptly realize infrared copy meter, first communication ends of described central control unit 1 is connected with the infrared communication interface 7 that is used to export information about power.The 38kHz modulation is used in the far infrared communication, and communication distance is not less than 5 meters.
By the long-range power consumption of examining each watt-hour meter, the second communication end of described central control unit 1 is connected with and is used for the power line carrier modem 6 that links to each other with many rates carrier meter reading concentrator 8 for convenient.
Metering module 2 adopts computation chip ADE7755, can accurately measure active energy, its mainly by A/D conversion, power calculation, electric energy add up, anti-shunt running etc. partly forms, and has highly reliable, high precision, low in power consumption.Electric energy meter adopts the transformer-supplied mode.The ADE7755 computation chip is converted to pulse respectively with electric energy respectively, finishes the electric pulse collection by central control unit 1 again, electric weight accumulative total.
The watt-hour meter of present embodiment is applied to pre-payment low-voltage power carrier automatic meter reading system, this system comprises: the band carrier interface, infrared interface, the RS485 interface, the microprocessor of display driver interface and system clock calendar, band high-precision A/D conversion, the ADE7755 computation chip of voltage/frequency conversion etc.This system also possesses multiple power on/off mode: during the carrier electric power table status, can carry out the remote on/off electric control; During IC-card pre-payment electric energy table status, after electric weight was used up, relay cut off the power supply automatically.
The foregoing description only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.And these belong to conspicuous variation or the change that spirit of the present utility model extended out and still are among the protection domain of the present utility model.
